Disclosed is a non-aqueous electrolyte containing a non-aqueous solvent, a solute dissolved in the non-aqueous solvent, and a hydrogenated terphenyl. The solute comprises an alkali salt containing boron and an alkali salt containing no boron. An amount of the hydrogenated terphenyl contained in the non-aqueous electrolyte is preferably 0.5 mass % to 3.5 mass %. For example, LiBF<SUB>4</SUB>, NaBF<SUB>4 </SUB>or KBF<SUB>4 </SUB>is used as the alkali salt containing boron, while LiPF<SUB>6</SUB>, LiClO<SUB>4</SUB>, LiAsF<SUB>6</SUB>, LiCF<SUB>3</SUB>SO<SUB>3</SUB>, LiN(SO<SUB>2</SUB>CF<SUB>3</SUB>)<SUB>2</SUB>, LiN(SO<SUB>2</SUB>C<SUB>2</SUB>F<SUB>5</SUB>)<SUB>2 </SUB>or LiC(SO<SUB>2</SUB>CF<SUB>3</SUB>)<SUB>3 </SUB>is used as the alkali salt containing no boron. |
